2012_Washington_wildfires
The 2012 Washington wildfires were a series of 1,342 wildfires that burned 259,526 acres (1,050 km2) over the course of 2012.[1] The fires primarily occurred in the Okanogan and Wenatchee National Forests during September and October 2012.[citation needed] A severe lightning storm on September 8 caused hundreds of fires across the east side of Cascade Range. Smoke caused hazardous air quality conditions in the cities of Ellensburg and Wenatchee,[2] and was noticeable in Seattle. The cost of fighting the largest four fires was estimated to be $67.5 million.[3]
